A pamphlet in retailers across Japan has revealed some new information about the upcoming release, Pokémon Mystery Dungeon Magnagate & The Infinite Labyrinth. This pamphlet mostly included information that has already been revealed but has contained some new information. First, it reconfirmed that the game features a single savefile, like previous Pokémon games. Second, it detailed the StreetPass feature of the game. Much like the WonderMail feature of past Dungeon games, with StreetPass, if you fall in battle during a Dungeon, you can set the mission to be rescued. If you pass anyone else with the game, the StreetPass feature will send them the mission to complete. We'll bring more as the game comes, and more news is expected in CoroCoro this week.

Well it's not surprising there would be a single save file for the game.

Not too sure about the Wonder Mail feature being implemented into StreetPass, because it would be likely you'd have to StreetPass said person twice to be rescued. Hmm, we'll see how that turns out.
